Police and airline officials say two United Airlines pilots have been arrested for suspected intoxication before they were to fly 141 passengers from Scotland to the United States.

United Airlines officials have confirmed Saturday's arrest of the pilots, aged 45 and 35, at Glasgow Airport. The Police Service of Scotland says both men are expected to be arraigned Monday at a court in Paisley, a Glasgow suburb, to face charges connected to Britain's transport safety laws.

United said Saturday's flight from Glasgow to the U.S. city of Newark, New Jersey, was delayed for 10 hours while the airline sought replacement pilots.
